Stevan Harnad and I seem to be thinking about many of the same issues. Sometimes we agree, sometimes we don't; but I always find his reasoning refreshing, his positions sensible, and the problems with which he's concerned to be of central importance to cognitive science. His "Grounding Symbols in the Analog World with Neural Nets" (= GS) is no exception. And GS not only exemplifies Harnad's virtues, it also provides a springboard for diving into Harnad- Bringsjord terrain.

This study presents a substantial and often radical reinterpretation of some of the central themes of Locke's thought. Professor Alexander concentrates on the Essay Concerning Human Understanding and aims to restore that to its proper historical context. In Part I he gives a clear exposition of some of the scientific theories of Robert Boyle, which, he argues, heavily influenced Locke in employing similar concepts and terminology. Against this background, he goes on in Part II to provide an account of (...) Locke's views on the external world and our knowledge of it. He shows those views to be more consistent and plausible than is generally allowed, demonstrating how they make sense and enable scientific explanations of nature. In examining the views of Locke and Boyle together, the book throws new light both on the development of philosophy and the beginnings of modern science, and in particular it makes a considerable and original contribution to our understanding of Locke's philosophy.

That Strong AI is still alive may have a lot to do with its avoidance of true tests.

It has been standard philosophical practice in analytic philosophy to employ intuitions generated in response to thought-experiments as evidence in the evaluation of philosophical claims. In part as a response to this practice, an exciting new movement—experimental philosophy—has recently emerged. This movement is unified behind both a common methodology and a common aim: the application of methods of experimental psychology to the study of the nature of intuitions. In this paper, we will introduce two different views concerning the relationship that (...) holds between experimental philosophy and the future of standard philosophical practice (what we call, the proper foundation view and the restrictionist view), discuss some of the more interesting and important results obtained by proponents of both views, and examine the pressure these results put on analytic philosophers to reform standard philosophical practice. We will also defend experimental philosophy from some recent objections, suggest future directions for work in experimental philosophy, and suggest what future lines of epistemological response might be available to those wishing to defend analytic epistemology from the challenges posed by experimental philosophy.

From its very beginnings, the social study of culture has been polarized between structuralist theories that treat meaning as a text and investigate the patterning that provides relative autonomy and pragmatist theories that treat meaning as emerging from the contingencies of individual and collective action-so-called practices-and that analyze cultural patterns as reflections of power and material interest. In this article, I present a theory of cultural pragmatics that transcends this division, bringing meaning structures, contingency, power, and materiality together in a (...) new way. My argument is that the materiality of practices should be replaced by the more multidimensional concept of performances. Drawing on the new field of performance studies, cultural pragmatics demonstrates how social performances, whether individual or collective, can be analogized systematically to theatrical ones. After defining the elements of social performance, I suggest that these elements have become "de-fused" as societies have become more complex. Performances are successful only insofar as they can "re-fuse" these increasingly disentangled elements. In a fused performance, audiences identify with actors, and cultural scripts achieve verisimilitude through effective mise-en-scène. Performances fail when this relinking process is incomplete: the elements of performance remain apart, and social action seems inauthentic and artificial, failing to persuade. Refusion, by contrast, allows actors to communicate the meanings of their actions successfully and thus to pursue their interests effectively. (shrink)
Is it true that if zombies-creatures who are behaviorally indistinguishable from us, but no more conscious than a rock-are logically possible, the computational conception of mind is false? Are zombies logically possible? Are they physically possible? This paper is a careful, sustained argument for affirmative answers to these three questions.
Martha Nussbaum proposes a universal list of human capabilities as the basis for fundamental political principles. She claims that the list, in an Aristotelian spirit, might be justified by an ongoing inquiry into valuable human functionings for the good life. Here I argue that the attractiveness of Nussbaum’s theory crucially depends on the philosophical possibility of a non-reductionist understanding of naturalism and on resolving the tensions between ethical and political aspects of the role of capabilities. Through a comparison of Nussbaum’s (...) approach with those of Aristotle and (less familiarly) Hume, I try to show that in these alternative versions we find valuable resources for the kind of non-reductionist model which might, in line with Nussbaum’s own objectives, provide the basis for a capabilities-based critique of dominant modes of normative theorizing and their influence in public discourse.

The Turing Test (TT) is claimed by many to be a way to test for the presence, in computers, of such ``deep'' phenomena as thought and consciousness. Unfortunately, attempts to build computational systems able to pass TT (or at least restricted versions of this test) have devolved into shallow symbol manipulation designed to, by hook or by crook, trick. The human creators of such systems know all too well that they have merely tried to fool those people (...) who interact with their systems into believing that these systems really have minds. And the problem is fundamental: the structure of the TT is such as to cultivate tricksters. A better test is one that insists on a certain restrictive epistemic relation between an artificial agent (or system) A, its output o, and the human architect H of A – a relation which, roughly speaking, obtains when H cannot account for how A produced o. We call this test the ``Lovelace Test'' in honor of Lady Lovelace, who believed that only when computers originate things should they be believed to have minds. (shrink)
Alan Turing devised his famous test (TT) through a slight modificationof the parlor game in which a judge tries to ascertain the gender of twopeople who are only linguistically accessible. Stevan Harnad hasintroduced the Total TT, in which the judge can look at thecontestants in an attempt to determine which is a robot and which aperson. But what if we confront the judge with an animal, and arobot striving to pass for one, and then challenge him to peg which iswhich? (...) Now we can index TTT to a particular animal and its syntheticcorrelate. We might therefore have TTTrat, TTTcat,TTTdog, and so on. These tests, as we explain herein, are abetter barometer of artificial intelligence (AI) than Turing's originalTT, because AI seems to have ammunition sufficient only to reach thelevel of artificial animal, not artificial person.

Evolutionary game theoretic accounts of justice attempt to explain our willingness to follow certain principles of justice by appealing to robustness properties possessed by those principles. Skyrms (1996) offers one sketch of how such an account might go for divide-the-dollar, the simplest version of the Nash bargaining game, using the replicator dynamics of Taylor and Jonker (1978). In a recent article, D'Arms et al. (1998) criticize his account and describe a model which, they allege, undermines his theory. I sketch a (...) theory of evolutionary explanations of justice which avoids their methodological criticisms, and develop a spatial model of divide-the-dollar with more robust convergence properties than the models of Skyrms (1996) and D'Arms et al. (1998). (shrink)

The dominant scientific and philosophical view of the mind – according to which, put starkly, cognition is computation – is refuted herein, via specification and defense of the following new argument: Computation is reversible; cognition isn't; ergo, cognition isn't computation. After presenting a sustained dialectic arising from this defense, we conclude with a brief preview of the view we would put in place of the cognition-is-computation doctrine.
Zlatev offers surprisingly weak reasoning in support of his view that robots with the right kind of developmental histories can have meaning. We ought nonetheless to praise Zlatev for an impressionistic account of how attending to the psychology of human development can help us build robots that appear to have intentionality.
You are offered one billion dollars to 'simply' produce a proof-of-concept robot that has phenomenal consciousness -- in fact, you can receive a deliciously large portion of the money up front, by simply starting a three-year work plan in good faith. Should you take the money and commence? No. I explain why this refusal is in order, now and into the foreseeable future.
After introducing a perspective on terrorism as postpolitical and after establishing the criteria for success that are immanent in this form of antipolitical action, this essay interprets September 11, 2001, and its aftermath inside a cultural-sociological perspective. After introducing a macro-model of social performance that combines structural and semiotic with pragmatic and power-oriented dimensions, I show how the terrorist attack on New York City and the counterattacks that immediately occurred in response can be viewed as an iteration of the performance/counterperformance (...) dialectic that began decades, indeed centuries, ago in terms of the relation of Western expansion and Arab-Muslim reaction. I pay careful attention to the manner in which the counterperformance of New Yorkers and Americans develops an idealized, liminal alternative that inspired self-defense and outrage, leading to exactly the opposite performance results from those the al-Qaeda terrorists had intended.

What''s computation? The received answer is that computation is a computer at work, and a computer at work is that which can be modelled as a Turing machine at work. Unfortunately, as John Searle has recently argued, and as others have agreed, the received answer appears to imply that AI and Cog Sci are a royal waste of time. The argument here is alarmingly simple: AI and Cog Sci (of the Strong sort, anyway) are committed to the view that cognition (...) is computation (or brains are computers); butall processes are computations (orall physical things are computers); so AI and Cog Sci are positively silly.I refute this argument herein, in part by defining the locutions x is a computer and c is a computation in a way that blocks Searle''s argument but exploits the hard-to-deny link between What''s Computation? and the theory of computation. However, I also provide, at the end of this essay, an argument which, it seems to me, implies not that AI and Cog Sci are silly, but that they''re based on a form of computation that is well beneath human persons.

The growth of managed care was accompanied by concern about the impact that changes in health care organization would have on the doctor-patient relationship (DPR). We now are in a "post-managed care era," where some of these changes in health care delivery have come to pass while others have not. A re-examination of the DPR in this setting suggests some surprising results. Rather than posing a new and unprecedented threat, managed care was simply the most recent of numerous strains on (...) the DPR that have occurred throughout the century. These strains are a constant, inevitable consequence of the varying needs and concerns of patient and physicians as they seek to balance their desires for a certain type of DPR with their simultaneous desire for other aspects of care such as lower costs, greater technological sophistication, and improved outcomes.

One of the most important contributions of the Parsonian tradition has been its conceptualization of the relative autonomy and mutual interpenetration of culture and social systems. The first part of this chapter defines three ideal types of empirical relationships between culture and society: specification, refraction, and columnization. Each is related to different configurations of social structure and culture and, in turn, to different degrees of social conflict. The second part of the chapter uses this typology to illuminate critical aspects of (...) the relationship between conflict and integration in the Watergate crisis in the U.S. (shrink)

Steven Pinker's How the mind works (HTMW) marks in my opinion an historic point in the history of humankind's attempt to understand itself. Socrates delivered his "know thyself" imperative rather long ago, and now, finally, in this behemoth of a book, published at the dawn of a new millennium, Pinker steps up to have psychology tell us what we are: computers crafted by evolution - end of story; mystery solved; and the poor philosophers, having never managed to obey Socrates' command, (...) are left alone to wander in the labyrinth of their benighted speculation forever. Unfortunately, though HTMW is to this point the crowning attempt of psychology to make systematic sense of persons by integrating everything relevant science knows, the book fails - and it fails so fundamentally and irremediably that we would do well to wonder anew whether we should supplant the basic view it promotes with what I call the super-mind hypothesis: the view that though mere animals are evolved computers, persons are more.

Though it''s difficult to agree on the exact date of their union, logic and artificial intelligence (AI) were married by the late 1950s, and, at least during their honeymoon, were happily united. What connubial permutation do logic and AI find themselves in now? Are they still (happily) married? Are they divorced? Or are they only separated, both still keeping alive the promise of a future in which the old magic is rekindled? This paper is an attempt to answer these questions (...) via a review of six books. Encapsulated, our answer is that (i) logic and AI, despite tabloidish reports to the contrary, still enjoy matrimonial bliss, and (ii) only their future robotic offspring (as opposed to the children of connectionist AI) will mark real progress in the attempt to understand cognition.

The original proof of the four-color theorem by Appel and Haken sparked a controversy when Tymoczko used it to argue that the justification provided by unsurveyable proofs carried out by computers cannot be a priori. It also created a lingering impression to the effect that such proofs depend heavily for their soundness on large amounts of computation-intensive custom-built software. Contra Tymoczko, we argue that the justification provided by certain computerized mathematical proofs is not fundamentally different from that provided by surveyable (...) proofs, and can be sensibly regarded as a priori. We also show that the aforementioned impression is mistaken because it fails to distinguish between proof search (the context of discovery) and proof checking (the context of justification). By using mechanized proof assistants capable of producing certificates that can be independently checked, it is possible to carry out complex proofs without the need to trust arbitrary custom-written code. We only need to trust one fixed, small, and simple piece of software: the proof checker. This is not only possible in principle, but is in fact becoming a viable methodology for performing complicated mathematical reasoning. This is evinced by a new proof of the four-color theorem that appeared in 2005, and which was developed and checked in its entirety by a mechanical proof system. (shrink)
Andrew Boucher (1997) argues that ``parallel computation is fundamentally different from sequential computation'' (p. 543), and that this fact provides reason to be skeptical about whether AI can produce a genuinely intelligent machine. But parallelism, as I prove herein, is irrelevant. What Boucher has inadvertently glimpsed is one small part of a mathematical tapestry portraying the simple but undeniable fact that physical computation can be fundamentally different from ordinary, ``textbook'' computation (whether parallel or sequential). This tapestry does indeed immediately imply (...) that human cognition may be uncomputable. (shrink)
Ethical business practices have been widely prescribed, but why? Consumers views on unethical business practices have been studied, but possibly more important to marketers and researchers are consumer actions and reactions to unethical business practices and the businesses themselves. Do consumers react negatively, or in such a way as to "punish" the unethical business? If so, what is the nature and extent of the punishment? This research seeks answers to these questions by examining consumer reactions, such as complaining and switching, (...) to instances of unethical business practices. Using equity theory, this research proposes that consumers should be willing to tolerate some unethical behavior as long as they feel their investments and outcomes remain proportionately equal. Consumers who perceive that their outcome/investment ratio is proportionately unequal to their comparison other will respond by switching or complaining. In this research consumers were exposed to two types of service failures with different levels of service recovery in vignettes. Costs incurred by the consumer during the service transaction were also manipulated in the vignettes. Significant differences were found for complaint behavior in the failure recovery vignettes tested. Specifically, voice complaint was higher in the high cost service encounters in both types of services tested. The recovery attempt used (ethical, unethical, or none) led to significance differences in the variables of complaint, voice complaint, satisfaction, and quality. Higher satisfaction and quality ratings were found for the ethical recovery attempt and higher intentions to use complaint and voice complaint in the unethical recovery attempts. One significant interaction between cost and recovery attempt was found. Intentions to use voice complaint were higher in the high cost situations of ethical and unethical recovery, while approaching equality at the no recovery attempt. (shrink)
The paper describes the refusal of the liberal community to assert the right of persons accused of mental illness to be free of coercive psychiatric intrusion. It suggests that the penchant for benevolent governmental intrusion into other social problems may be at fault and recommends that intervention be abandoned in favor of a return to human autonomy as a basis of the concept of freedom.
In his recent _The Rediscovery of the Mind_ John Searle tries to destroy cognitive science _and_ preserve a future in which a ``perfect science of the brain'' (1992, p. 235) arrives. I show that Searle can't accomplish both objectives. The ammunition he uses to realise the first stirs up a maelstrom of consciousness so wild it precludes securing the second.
Does what guides a pastry chef stand on par, from the standpoint of contemporary computer science, with what guides a supercomputer? Did Betty Crocker, when telling us how to bake a cake, provide an effective procedure, in the sense of `effective' used in computer science? According to Cleland, the answer in both cases is ``Yes''. One consequence of Cleland's affirmative answer is supposed to be that hypercomputation is, to use her phrase, ``theoretically viable''. Unfortunately, though we applaud Cleland's ``gadfly philosophizing'' (...) (as, in fact, seminal), we believe that unless such a modus operandi is married to formal philosophy, nothing conclusive will be produced (as evidenced by the problems plaguing Cleland's work that we uncover). Herein, we attempt to pull off not the complete marriage for hypercomputation, but perhaps at least the beginning of a courtship that others can subsequently help along. (shrink)
